DANGER!
Never attempt to connect gensets to the same busbar if they do not have the same phase rotation.
DANGER!
Do not use this parameter to attempt to correct for incorrect wiring of the controller's AC measurement terminals. Rewire
the terminals correctly.
3.1.2 [Source] and [Busbar] for each controller type
The following table shows the names used for [Source] and [Busbar] for the AC configuration of each controller type.
Controller type
[Source] (ACM3.1 terminals 5 to 8)
[Busbar] (ACM3.1 terminals 1 to 4)
GENSET
Generator
Busbar
EMERGENCY genset

3.1.3 [Source] AC configuration
You can configure the source's AC configuration under
Configure > Parameters > [Source] > AC setup
.
Voltage transformer
These parameters relate to the terminals on the ACM3.1. Configure these parameters under
Configure > Parameters > [Source] >
AC setup > Voltage transformer
.
You must set these parameters if there is a voltage transformer on the source's voltage measurement.
If
Primary
:
Secondary
ratio is 1, the controller uses the voltage measurement without any correction for a voltage transformer.
The controller does not need information about the voltage transformer type (for example, open delta, star-star, and so on).
